java - HibernateTemplate 更新查询

Question

如何使用hibernate模板使用hql更新查询这是hql语句“update Login set empSmartId = 48750005”+“其中empPassword = 6328ef1675ddb7106eba8dc2661961d7”

使用 getHibernatetemplate()

当前代码:

 public class LoginDaoImp extends HibernateDaoSupport implements LoginDao { 
public boolean resetAttempt(Login login) { 
try { login.setAttempt(0); 
getHibernateTemplate().update(login); 
return true; 
} catch (Exception e) { e.printStackTrace(); } 
return false; } 
i can save whole pojo class above code work but i want to use where condition to update only hibernateTemplate to update the data

你会看起来像这样

public class LoginDaoImp extends HibernateDaoSupport implements LoginDao 
{ 
    public boolean resetAttempt(Login login) 
    { 
        try 
        { 
            // you should create method for login to retrived based on password
            //Remember getting login  by password is not correct way, Instead you you should use primary key
            //Getting persisted object of Login
            Login persisted_login = getLoginByPassword(6328ef1675ddb7106eba8dc2661961d7);

            //Setting value in persisted object of Login
            persisted_login.setEmpSmartId (48750005); 
            getHibernateTemplate().update(persisted_login); 
            return true; 
        } catch (Exception e) { 
            e.printStackTrace(); 
        } 
        return false; 
    }
}
